Customer Question

I have a hot tub problem. My motor is spinning free. The low motor runs every once in a while. I bought a new tub switch and plugged it in and it did not get the tub running. When i clicked the switch i would get a loud buzz sound. The heater is working. It was up to 103. The tub has not worked for a week now and the temp is down to 75. There is a Sn code that is on the switch screen.

this is a high temp limit fail..likely because flow was lost when heating.
This is a critical error and really should be looked at by a professional unless you are very well versed in using a meter and testing sensors.
